Audio-Technica AT4033A
Cardioid Condenser Microphone with Shockmount and Case

OUR PART #  AT4033A


The Audio-Technica AT4033A is a side-address microphone that offers low-noise, symmetrical, transformerless circuitry that results in exceptional transient response and clean output signals. A strong up-front presence characterizes the sonic signature of this 40 Series pro-audio classic. The AT4033a’s 80Hz high-pass filter easily switches between flat frequency response and a low-end roll-off that diminishes ambient noise and popping with closely-miked vocals. Includes the AT8449a shock mount for superior isolation.

Audio-Technica AT4033A Features:

  • Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of high-speed transients
  • Precision-machined, nickel-plated brass, acoustic element baffle provides enhanced element stability and optimal sensitivity
  • The 2-micron-thick, vapor-deposited gold diaphragm undergoes a five-step aging process so that the optimum characteristics achieved remain constant over years of use
  • Floating-construction capsule assembly provides isolation from noise and vibration
  • Open acoustical environment of the symmetrical housing assembly minimizes unwanted internal reflections
  • State-of-the-art surface-mount electronics ensure compliance with A-T's stringent consistency and reliability standards'
  • Custom shock mount provides superior isolation
